[Help] SIM slot contact broken
#2
This is a "design flaw", if you do not remove it properly then the SIM slips out of the micro-SIM adapter and the adapter can hook on the contact and break it.

According to the manual we have the following contacts

USIM_VDD pin 14 PO Power supply for (U)SIM card

USIM_DATA pin 15 IO Data signal of (U)SIM card

USIM_CLK pin 16 DO Clock signal of (U)SIM card

USIM_RST pin 17 DO Reset signal of (U)SIM card

USIM_PRESENCE pin 13 DI (U)SIM card insertion detection

USIM_GND pin 10 Specified ground for (U)SIM card

I don't know which pin is this but probably if it's the Reset signal you won't have problem.

When you want to remove the SIM you should always press and slide out at the point where the metallic envelope ends and always above the motherboard, not above the gap for the battery, if the SIM slips out of the micro-SIM adapter then you reinsert again and retry.

I would fold a small aluminum foil block to restore the contact, the same way I electrically ground the smartphone and tablet motherboards when I fix them, I fold aluminum foil strips and stick them with tape.

As I can see from the photo it is a very shuttle situation where you have to avoid contact with the metallic envelope. It would be helpful if you can open the case and find which contact is this. You can find the hardware manual in this thread.
